What people are saying about Propeller

“Asthma can make a lot of things in your life just a little more challenging. We all get busy and you can have a tendency to just deal with things being harder, but the weekly emails helped remind me to take some time to check in with myself to see how I was doing and actually focus on making sure I'm managing my asthma as well as I can be.”

Katherine,Propeller member

“Real-time monitoring makes earlier management changes possible. We can focus on patients who are having problems, foregoing the need to make appointments for patients who are doing well.”

Dr. Merchant,Allergist, Dignity Health

“My biggest 'wow' moment was getting a text message that my son used his inhaler”
